Windows 10 1511 update and GTC plugin

After install the Windows 10 1511 update, the aruba EAP-GTC fails to authenticate.  Aruba OS is 6.4.4.2.  Has any else experienced this?

Did it work before the update?  I assume you are using termination and connecting from the controller to an LDAP server?

It was tracked down to this update.  A clean Windows 10 machine without the update was able to login.  Same machine was upgraded with 1511 and now fails to login.  Sometimes nothing happens, sometimes the GTC plugin login screen appears.  Nothing appears in the GTC plugin logs that is abnormal.

Thank you.

 

What is your setup?  Are you using termination on the controller pointing to an LDAP server?  How many clients do you have?

3600 Controller tied to LDAP feeding a FW.  About 75 users.  Primarily OSX.  All OSX clients can connect without a problem.  Windows clients cannot connect using Aruba GTC-plugin if they installed the 1511 update.   They can connect without GTC however (i.e. bypassing/not using the plugin).

Please see if anything is in the log here:  \Windows\Tracing\eap-gtc.log.

To get more detail on the client here by typing this:

Netsh ras set tracing eap-gtc enable

Also, please try the workaround on a single Windows client here:  http://answers.microsoft.com/en-us/windows/forum/windows_10-networking/after-update-to-1511-i-cant-connect-via-wlan-to-my/696f12ed-6e08-4e14-ae30-c7a878ebbd17?auth=1 to see if the problem is fixed.

That does work, but unfortunately this forces TLS 1.0 which has known issues.

Well it didn't have any issues until Microsoft Released their patch.

 

There is an open case and it is targeted to be fixed in the next 6.4.4.x  You need to use the workaround until then.

 

Between you and me, as a more long-term solution, you shold possibly look into a radius server that handles TLS 1.2 properly, otherwise these client patches will continue to break your network.

Can you confirm if Aruba OS 6.4.4.4 fixes this issue?
